Hepatic Portal Circulation | Drains the digestive organs, spleen, and pancreas and deliver this blood to the liver through the hepatic portal vein |
Which portal has a unique and unusual circulation | Hepatic Portal Circulation |
Vital Signs | Arterial Pulse and Blood Pressure and Respiratory Rate |
Pulse | A pressure wave that occurs with each beat of the left ventricle |
What is the pulse average beats per minute? | 70-75 |
Pressure Points | Points at the body surface where the pulse may be felt |
Blood Pressure | The pressure the blood exerts against the inner walls of the blood vessels, it is the only force that keeps blood circulating continuously even between heartbeats |
Arterial Pulse | Pressure wave of blood that can only be felt in the arteries. |
Systolic Pressure | The pressure in the arteries at the peak of ventricular contraction |
Diastolic Pressure | The pressure when the ventricles are relaxing. |
How is blood pressure measured? | Millimeters of mercury (mm/Hg) |
Peripheral Resistance | The amount of friction the blood encounters as it flows through the blood vessels |
Vasocontriction | Narrowing of the blood, the major action of the sympathetic nervous system |
What major role do the kidneys play in the cardiovascular system? | Regulate blood pressure by altering blood volume |
What are the 5 effects on blood pressure? | 1. Neural Factors: Autonomic Nervous System, 2. Renal Factors:Kidneys,. 3. Temperature, 4. Chemicals, 5. Diet |
How does temperature affect blood pressure? | Cold has a vasoconstricting effect while heat has a vasodilating effect |
How does chemicals effect blood pressure? | Drugs, Alcohol, Nicotine can increase blood pressure causing vasocontriction |
How does diet effect blood pressure? | Foods low in salt and sodium can help to prevent hypertention |
What is the normal systolic blood pressure? | 110-140 mm Hg |
What is the normal diastolic blood pressure | 70-80 mm Hg |
Hypotension | Low blood pressure with a systolic below 100 mm Hg |
Orthostatic Hypotension | Temporary Low Pressure from suddenly changing positions |
Hypertension | High Blood Pressure that is 140/90 of higher |
What is the percentage of people with primary or essential hypertension? | 90% |
